Help!

Not quite John, Paul, George and Ringo but it's the flag that does it.

These 4 are missing 2 mates, bag man and man in coat. They may yet be in another box in the loft, but originally a set of 6 by Dinky made in 1964.

They make me remember my train mad dad, who would have bought these...as a 29 year old. Grow up Philip.
